Hello, I am looking for a board to add 12-bit ADC values in a 32 bit value. I have looked at the arduino due, but 32b math on a 16 arduino might be OK. Here are general questions: -which board? This doesn't have to be super-fast, 1000 conversions per second good. -should add the ADC value to a 32 bit location. -32 bit number should be periodically inspectable. -programming exanples show use of 32b math. (adds)

I have looked at due. But haven't found anywhere use of 32 bit math. My guess was it should do 32 bit since its a 32b chip. But I haven't found any examples of that, just general statements that its programming is similar to the arduino-16.

So: This question may devolve into: 16 or 32? (assuming 32b math can be done on the 16)

Any help appreciated. TIA John
